Professor Charles Norman MacLeod

Electronic and Electrical Engineering

Personal statement

Charles MacLeod is a Professor in the Centre for Ultrasonic Engineering. 

He is the Babcock International Group / Royal Academy of Engineering Chair in Sensor-Driven Automated Welding.

He is director of the Sensor Enabled Automation & Robotics Control Hub (SEARCH), a £24M research innovation and technology transfer laboratory. Aligned to this, he is Course Director of the Autonomous Robotic Intelligent Systems (ARIS) MSc.

His research is primarily associated with the inspection and manufacturing enhancement of high-value assets and components, where he leads a number of high-profile inter-disciplinary in-process welding and metal additive research projects.

He has driven and co-developed core robotic and ultrasonic technology from fundamental EPSRC research, which is now being licensed by a leading industrial organisation and co-developed an innovative inspection robot for a critical life-extension inspection at Sellafield Reprocessing Facility.

He is the PI and designer of the Engaging Robotic Interactive Cell (ERIC) STEM Outreach cell. 

His research interests include:

Non-Destructive Evaluation

In-Process Inspection of Fusion Welding & Metal Additive Components

Sensors including Ultrasonic, Electromagnetic, Tactile and Visual

Automation & Robotics 

Automated Manufacturing & Welding

Teaching Activities.

Course Director: Autonomous Robotic Intelligent Systems (ARIS) MSc.

Module Registrar: EE987 Sensors & Instrumentation

Lecturer: EE312 Instrumentation and Microcontrollers

Investigating the effect of residual stress on hydrogen cracking in multi-pass robotic welding and additive manufacturing
Javadi, Yashar (Principal Investigator) MacLeod, Charles Norman (Co-investigator) Alipooramirabad, Houman (Co-investigator)
The aim of this project is the development of a round-robin Residual Stress (RS) measurement to investigate the effect of the ‎RS on hydrogen cracking. ‎Dr Javadi ‎(PI) is leading the RS area in the Center for Ultrasonic Engineering (CUE) and he has been a Keynote Speaker at ‎the 11th International Conference on Residual Stress (ICRS 11) where he presented his novel idea on RS ‎measurement using the Phased Array Ultrasonic Testing (PAUT) method [1]. This method will also be used ‎to study the effect of RS on hydrogen cracking. In this Strathclyde-ANSTO collaboration, ANSTO will conduct the Neutron ‎Diffraction (ND) to form the round-robin RS measurement project. ‎
